hypnosec writes "Stephen Hawking's ability to communicate has been deteriorating over the years and as it stands, he is only able to communicate at the rate of 1 word per minute. Intel CTO Justin Rattner has revealed that they are working on an interface that will boost the scientist's speech to up to 10 words per minute. Beyond twitching his cheek, Hawking is also capable of other voluntary facial expressions which can be tapped to achieve faster communications with the help of a better character interface and a better word predictor."

dgharmon writes in with an interesting article about how much (or how little) beef is in a UK burger. "The presence of horsemeat in value beefburgers has caused a furore. But what is usually in the patties? It has been a sobering week for fans of the beefburger. Tesco have used full-page adverts in national newspapers to apologize for selling burgers in the UK that were found to contain 29% horsemeat. Traces of horse DNA were also detected by the Food Standards Agency of Ireland in products sold by Iceland, Lidl, Aldi and Dunnes. But a beefburger rarely contains 100% beef."

First time accepted submitter ggrocca writes "Using human mucus as a testbed for how well influenza virus thrives in different humidity conditions, researchers at Virginia Tech found that the virus survived best if humidity is below 50%, a typical indoor situation during the winter in temperate climates due to artificial heating. The virus begins to find itself at home again only when humidity reaches almost 100%. Unsurprisingly, the latter finding explains flu spikes during rainy season in tropical climates. Full paper on PLOS ONE."

MightyMartian writes "NASA scientists say Cassini has discovered that far fewer craters are visible on Titan than on the other moons of Saturn. The craters they have discovered are far shallower than other moons' craters and appear to be filling with hydrocarbon sand. On top of being another reason Titan's active geology is very cool, it adds to the mystery of where all the methane on Titan is coming from. 'The rain that falls from Titan's skies is not water, but contains liquid methane and ethane, compounds that are gases at Earth's temperatures. ... The source of Titan's methane remains a mystery because methane in the atmosphere is broken down over relatively short time scales by sunlight. Fragments of methane molecules then recombine into more complex hydrocarbons in the upper atmosphere, forming a thick, orange smog that hides the surface from view. Some of the larger particles eventually rain out onto the surface, where they appear to get bound together to form the sand.'"

New submitter EngnrFrmrlyKnownAsAC writes "Communicating with lasers has become the hot new thing. While most researchers are seeking faster throughput, NASA set its sights in a different direction: the moon. They recently announced the first successful one-way laser communication 'at planetary distances.' What did they send? An image of the Mona Lisa, of course. 'Precise timing was the key to transmitting the image. Sun and colleagues divided the Mona Lisa image into an array of 152 pixels by 200 pixels. Every pixel was converted into a shade of gray, represented by a number between zero and 4,095. Each pixel was transmitted by a laser pulse, with the pulse being fired in one of 4,096 possible time slots during a brief time window allotted for laser tracking. The complete image was transmitted at a data rate of about 300 bits per second.'"

dstates writes "The Department of Health and Human Services has released newly revised rules for the Health Information Privacy and Accountability Act (HIPAA) to ensure patient access to electronic copies of their electronic medical records. Several years ago, there was a great deal of excitement about personalized health information management (e.g. Microsoft HealthVault and Google Health). Unfortunately, patients found it difficult to obtain their medical records from providers in formats that could easily be imported. Personalized health records were time consuming and difficult to maintain, so these initiatives have not lived up to their expectations (e.g. Google Health has been discontinued). The new rules should address this directly and hopefully will revitalize interest in personal health information management. The new HIPAA rules also greatly strengthen patient privacy, the ability of patients to control who sees their medical information, and increases the penalties for leaking medical records information. 'Much has changed in health care since HIPAA was enacted over fifteen years ago,' said HHS Secretary Kathleen Sebelius. 'The new rule will help protect patient privacy and safeguard patients' health information in an ever expanding digital age.'"

sciencehabit writes with this excerpt from Science Magazine "Last November, astronomer David Turner made headlines by claiming that one of the sky's best known objects—the North Star, Polaris—was actually 111 light-years closer than thought. If true, the finding might have forced researchers to rethink how they calculate distances in the cosmos as well as what they know about some aspects of stellar physics. But a new study argues that distance measurements of the familiar star made some 2 decades ago by the European Space Agency's venerable Hipparcos satellite are still spot on."

sciencehabit writes "Scientists have found that, when it comes to mental recall, people are far more likely to remember the text of idle chitchat on social media platforms like Facebook than the carefully crafted sentences of books. The team gathered 200 Facebook posts from the accounts of undergraduate research assistants, such as 'Bc sometimes it makes me wonder' and 'The library is a place to study, not to talk on your phone.' They also randomly selected 200 sentences from recently published books, gathered from free text on Amazon.com. Sentences included, 'Underneath the mass of facial hair beamed a large smile,' and 'Even honor had its limits.' Facebook posts were one-and-a-half times as memorable as the book sentences (abstract). The researchers speculate that effortless chatter is better than well-crafted sentences at tapping into our minds' basic language capacities — because human brains evolved to prioritize and remember unfiltered information from social interaction."

dsinc sends this news from the University of Cambridge:
"For the last ten years, theoretical physicists have shown that the intense connections generated between particles as established in the quantum law of ‘entanglement’ may hold the key to eventual teleportation of information. Now, for the first time, researchers have worked out how entanglement could be 'recycled' to increase the efficiency of these connections. Published in the journal Physical Review Letters, the result could conceivably take us a step closer to sci-fi style teleportation in the future, although this research is purely theoretical in nature. ... Previous teleportation protocols have fallen into one of two camps, those that could only send scrambled information requiring correction by the receiver or, more recently, "port-based" teleportation that doesn't require a correction, but needs an impractical amount of entanglement – as each object sent would destroy the entangled state. Now, physicists from Cambridge, University College London, and the University of Gdansk have developed a protocol to provide an optimal solution in which the entangled state is 'recycled,' so that the gateway between particles holds for the teleportation of multiple objects. They have even devised a protocol in which multiple qubits can be teleported simultaneously, although the entangled state degrades proportionally to the amount of qubits sent in both cases."

Press2ToContinue sends this quote from a European Space Agency news release:
"ESA's Mars Express imaged the striking upper part of the Reull Vallis region of Mars with its high-resolution stereo camera last year. Reull Vallis, the river-like structure in theseimages, is believed to have formed when running water flowed in the distant martian past, cutting a steep-sided channel through the Promethei Terra Highlands before running on towards the floor of the vast Hellas basin. This sinuous structure, which stretches for almost 1500 km across the martian landscape, is flanked by numerous tributaries, one of which can be clearly seen cutting in to the main valley towards the upper (north) side."

cylonlover writes "Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals (abstract), his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills."

An anonymous reader writes "The Scientific and Technical Research Council of Turkey (TÜBITAK) has put a stop to the publication and sale of all books in its archives that support the theory of evolution, daily Radikal has reported. The books have long been listed as “out of stock” on TÜBTAK's website, but their further publication is now slated to be stopped permanently. Titles by Richard Dawkins, Alan Moorehead, Stephen Jay Gould, Richard Levontin and James Watson are all included in the list of books that will no longer be available to Turkish readers. In early 2009, a huge uproar occurred when the cover story of a publication by TÜBITAK was pulled, reportedly because it focused on Darwin’s theory of evolution."

An anonymous reader writes "Dozens of volunteers who anonymously donated their genomic data to a public database for medical research have been identified by a team led by Yaniv Erlich, a former computer security researcher turned geneticist. Erlich's team matched Y chromosomal markers in genomes compiled by the 1000 Genomes Project with non-anonymous genomic databases, for example some assembled from contributions by family tree enthusiasts (abstract). After finding a match on a presumed relative of the study participant, the researchers pieced together the relative's family tree through search engines and the like, until they were able to identify the participant based on gender, age, place of birth, and other supposedly 'non-identifying' information associated with the genome. The names of the identified participants have not been released."

ananyo writes "Mathematicians plan to launch a series of free open-access journals that will host their peer-reviewed articles on the preprint server arXiv. The project was publicly revealed in a blog post by Tim Gowers, a Fields Medal winner and mathematician at the University of Cambridge, UK. The initiative, called the Episciences Project, hopes to show that researchers can organize the peer review and publication of their work at minimal cost, without involving commercial publishers. 'It’s a global vision of how the research community should work: we want to offer an alternative to traditional mathematics journals,' says Jean-Pierre Demailly, a mathematician at the University of Grenoble, France, who is a leader in the effort. Backed by funding from the French government, the initiative may launch as early as April, he says."
